Quality of the studies was assessed using the National Institute for Health and Care Excellence tool. Meta-analysis used mean differences and standard deviations as summary statistics for the difference between bone age BA and chronological age CA. Of the 49 eligible studies, 35 were appropriate for further meta-analysis. The online version of this article Determining maturity and understanding growth in a child is critical for medical and psychosocial purposes.

Reliability of the Greulich & Pyle Method for Bone Age Estimation in a Spanish Sample

In the past, determination of bone maturity relied on visual evaluation of skeletal development in the hand and wrist, most commonly using the Greulich and Pyle atlas. The Gilsanz and Ratib digital atlas takes advantage of digital imaging and provides a more effective and objective approach to assessment of skeletal maturity. The atlas integrates the key morphological features of ossification in the bones of the hand and wrist and provides idealized, sex- and age-specific images of skeletal development.

Bone Age enables users to rapidly browse through the set of idealized atlas images and select the one that best matches the image being interpreted.

The calculated deviation of the patient's age from the normal range is immediately presented to help predict possible growth delays. This easy-to-use atlas and the related App will be invaluable for radiologists, endocrinologists, and pediatricians and also relevant to forensic physicians.

Gilsanz received his medical degree and his Ph. As Director of Imaging Research, Dr. Gilsanz oversees investigators and assists in their research relating to the advancement of the use of imaging technology and the development of imaging markers related to pediatric disease risk. He has conducted many novel investigations on the determinants and regulators of bone accrual during childhood and puberty.

Ratib is board certified in Cardiology and Nuclear Medicine who obtained his medical degrees at the University of Geneva and a Ph. He was appointed as Professor and Vice Chairman of the Department of Radiology at UCLA from to when he returned to Geneva to be appointed as chair of the department of medical imaging and head of the division of Nuclear medicine. In his current position he is responsible of six clinical divisions including radiology, neuroradiology, radio-oncology, nuclear medicine and medical informatics as well as a cyclotron and pre-clinical imaging unit.

He is also founding member and president of the OsiriX foundation, a non-profit organization for the promotion of Open-Source software in medicine. Skip to main content Skip to table of contents.

Nov Taskforces. It might be unknown or intentionally falsified e. However, most commonly, age determination is needed for young asylum seekers. Every year, young unaccompanied asylum seekers arrive in European countries, many without knowing how old they are or unable to provide formal documentation of their age. To ensure that children receive their rights and that adults are not treated as children, it is necessary to assign a chronological age to these individuals. Evaluation of skeletal maturation of the hand development has been used for age assessment of asylum seekers in many countries.

Hand Bone Age

Bone age is the degree of maturation of a child's bones. As a person grows from fetal life through childhood, puberty , and finishes growth as a young adult, the bones of the skeleton change in size and shape. These changes can be seen by x-ray techniques.

The main bone age assessment methods are the Greulich-Pyle and Tanner-Whitehouse 2 methods, both of which involve left hand and wrist radiographs. Several other bone age assessment methods have been developed, including ultrasonographic, computerized, and magnetic resonance MR imaging methods. The ultrasonographic method appears unreliable in children with delayed and advanced bone age. MR imaging is noninvasive; however, bone age assessment using MR imaging is relatively new, and further examinations are needed. An automated method for determining bone age, named BoneXpert, has been validated for Caucasian children with growth disorders and children of various ethnic groups. Sex hormones are necessary for bone growth and maturation in children with a bone age corresponding to normal pubertal age, and estrogen is essential for growth plate closure.

DOI: As an indicator of growth rate, bone age is used to determine the level of development and to predict chronological age when this is not known. The mean difference between the bone and chronological ages was 0. Given the systematic errors with regard to the reference population, we propose the adjustment required to apply the ages calculated according to the atlas and indicate the limitations inherent to predicting chronological age when only information from the bones in the hand and wrist is used. The technological, social and political upheavals of the past few years have modified lifestyles, revolutionised economies and caused the downfall of numerous companies and the emergence of many others in light of the new business opportunities created. In addition, the regional instability caused by armed conflicts has caused, and is currently causing, many people to seek refuge in more stable settings [1,2].

This study assesses the value of the Greulich and Pyle method in determining the skeletal ages of healthy American children of European and African descent born after the year The hand and wrist radiographs of children boys, girls; European-Americans [EA], African-Americans [AA] , ages 0 to 19 y, were analyzed by two experienced pediatric radiologists blinded to the chronological age of the subjects.

Metrics details. Skeletal age SA is considered the best method of assessing biological maturation. The aim of this study was to determine intra-observer reproducibility and inter-observer agreement of SA values obtained via the Greulich-Pyle GP method. In addition, the variation in calculated SAs by alternative GP protocols was examined. The sample was composed of Portuguese female soccer players aged The radiographs were examined using alternative GP protocols: wholeGP the plate was matched to the atlas as an overall approach; boneGP bone-by-bone inspections of bones; GPpmb bone-by-bone inspections of the pre-mature bones only. Inter-observer agreement participants multiplied by 30 bones was
